BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a pair glass window and door system having a remote controllable auto blind accommodated in a pair glass structure, more particularly to a pair glass window and door system equipped with a remote controllable auto blind, which is installed in buildings in order to improve an awning effect, protect a private life and reduce energy consumption while improving convenience of use and preventing disease-causing bacteria, such as mites or viruses, from parasitically existing in a residential area by accommodating the remote controllable auto blind (such as, a corrugated fabric sheet type blind or a multi-step horizontal slat type blind where the disease-causing bacteria may parasitically exist) in a closed-type pair glass structure.

2. Description of the Related Art

In most of conventional blind structures, a blind is suspended to a front upper wall section of a window frame without using a pair glass structure. Although some conventional blind structures including blinds accommodated in pair glass structures have been partially used for a single window and door system fixed to a wall section, such a conventional blind structure causes a problem in that a power supply cable plug extending from the conventional blind structure must be electrically connected to a power supply socket fixed to the wall section in order to supply power to the conventional blind structure. Thus, there is a difficulty to employ a pair glass window and door system equipped with the auto blind for a sliding window or a casement window of a building due to the difficulty of power supply.

In addition, most of the conventional blind structures may control only one blind with a cabled power supply structure in which a power supply wiring is exposed to an exterior. Even in a conventional blind structure capable of automatically controlling the blind, a sensor or a signal receiving part thereof is exposed to the exterior, so the conventional blind structure is not adaptable for a movable window and door system. In addition, since the power supply wiring, the sensor and the signal receiving part are exposed out of the conventional blind structure, the conventional blind structure is unfavorable in view of an internal decoration of a building.

According to the conventional blind structure, a control unit including the sensor and the signal receiving part exposed to the exterior may control the length of the blind by using a mechanical switch. In this case, a maximum development length and a minimum development length of the blind must be previously set when fabricating the blind such that the length of the blind can be adjusted by using the mechanical switch, so a user cannot reset or change the maximum and minimum development length of the blind. In addition, in a case of a remote controllable blind structure, since the sensor for receiving an infrared signal is exposed out of the blind structure, an external appearance of the remote controllable blind structure may be deteriorated. In addition, the infrared signal may be interrupted if obstacles exist at the outer portion of the blind structure.

Furthermore, according to the characteristics of the conventional blind structure, a motor is directly controlled by means of the sensor exposed out of the blind structure so as to control the operation of the single blind. Therefore, if a blind structure including a plurality of movable doors, that is, a pair glass window and door system equipped with a plurality of blinds is installed in a window frame or a door frame, it is difficult to individually or integrally control the operation of blinds.

Besides the above problems, if over-current is applied to the motor, the motor may be damaged or the window may be opened or closed. For this reason, it is necessary to install a special power supply wiring instead of a general power supply wiring in order to automatically operate the blind.

Therefore, there is a necessity for a blind structure in the form of a pair glass window and door system equipped with a remote controllable auto blind, in which the blind is movably accommodated, a sensor and/or a signal receiving section required for automatically controlling the blind are installed in a pair glass structure such that they are not exposed to an exterior, the blinds installed in a plurality of door frames can be individually or integrally remote-controlled regardless of obstacles, and a motor can be protected from over-current with a power supplying wiring system using an improved power supply terminal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Reference will now be made in detail to the preferred embodiment of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

Hereinafter, a preferred embodiment of the present invention will be explained with reference to the accompanying drawings.

As described above, a pair glass window and door system equipped with a remote controllable auto blinds (which can be simply referred to as “pair glass window and door system”) according to the present invention signifies a window and door system including various kinds of blinds accommodated in pair glass structures installed in a window frame and/or a door frame. Herein, the pair glass structure signifies a glass structure including spacers, such as aluminum spacers, and glasses attached to front and rear portions of the spacers such that the front and rear potions of the spacers are sealed by means of the glasses. In the following description, the term “pair glass” means the above glass structure.

According to the present invention, the pair glass window and door system may include a single window and door system equipped with a single blind installed in a single pair glass structure or a multiple window and door system including a plurality of blinds accommodated in pair glass structures installed in a window frame or a door frame. Blinds of the pair glass window and door system can be individually or integrally remote-controlled by controlling a motor. In addition, the blinds include corrugated fabric sheet blinds, multi-step horizontal slat type blinds or roll type blinds, which can be moved up and down while maintaining various angular positions by means of the motor.

FIG. 1 is a perspective view showing a pair glass window and door system equipped with remote controllable multi-step horizontal slat type blinds accommodated in pair glass structures installed in a window frame or a door frame according to one embodiment of the present invention, FIG. 2 is an exploded perspective view showing a pair glass structure including the remote controllable multi-step horizontal slat type auto blind used for a pair glass window and door system according to one embodiment of the present invention, and FIG. 3 is a perspective view showing a pair glass structure equipped with a corrugated fabric sheet blind.

Referring to FIGS. 1 to 3, the pair glass window and door system (200; 200A and 200B) of the present invention includes auto blinds accommodated in pair glass structures. The pair glass window and door system 200 is installed in a window frame or a door frame in a building for various purposes. The pair glass window and door system 200 can be configured with various constructions according to the structures of the window frame and the door frame, or installation purposes thereof.

For instance, as shown in FIG. 1, the pair glass window and door system 200 can be installed in a window frame of a building having slide rails at an upper portion or a lower portion thereof in such a manner that the pair glass window and door system 200 may act as a sliding window capable of slidably moving along the slid rails. In addition, the pair glass window and door system 200 can be installed in a window frame having no slide rails as a fixing window and can be installed in the window frame as a complex window having the sliding and fixing functions. It is noted that the pair glass window and door system according to the present invention is not limited to one of the above windows, but may include all of the above windows.

Hereinafter, the pair glass window and door system according to the present invention installed in a window frame having a slide rail will be described.

The pair glass window and door system 200 according to the present invention includes a pair glass structure as shown in FIGS. 2 and 3, a door frame 220 surrounding the pair glass structure, and a blind driving unit 100 (see, FIG. 6) for driving a blind 240 or 240 a fixed to an inner upper portion of the pair glass structure. The blind 240 or 240 a is accommodated in the pair glass structure while being suspended to the inner upper portion of the pair glass structure in such a manner that the blind 240 or 240 can be developed or shrunken under the remote-control of the blind driving unit 100.

According to one embodiment of the present invention, the slide rail formed in the window frame includes a slide protrusion 325 b and a slot 325 a. In addition, the door frame 220 of the pair glass window and door system 200 includes a slide slot 225 and a protrusion 225 b corresponding to the slide protrusion 325 b and the slot 325 a, so that the pair glass window and door system 200 can be movably installed in the window frame.

It is noted that such a slide rail is not an essential element of the present invention. That is, the sidle rail is not necessary if a non-slide type pair glass window and door system is provided.

As described above, the pair glass structure can be fabricated by attaching glasses to front and rear portions of spacers such that the front and rear portions of spacers can be sealed by means of the glasses. As shown in FIGS. 2 and 3, the pair glass structure includes spacers 220 a, 220 b, 220 c and 220 d, and pair glasses 270 attached to front and rear portions of spacers 220 a, 220 b, 220 c and 220 d such that the spacers 220 a, 220 b, 220 c and 220 d can be sealed by means of the pair glasses 270. The blind 240 or 240 a is fixedly suspended to an upper portion of a closed cavity defined by the spacers 220 a, 220 b, 220 c and 220 d and the pair glasses 270.

At this time, it is possible to inject gas into the closed cavity in order to improve thermal insulation performance of the closed cavity and to prevent the closed cavity from being shrunken due to thermal shrinkage.

As mentioned above, various kinds of blinds driven by a motor can be used for the present invention. For example, in a case of the multi-step horizontal slat type blind shown in FIG. 2, a plurality of horizontal slats 240 are suspended to an upper support section 210 of the closed cavity formed between the pair glasses 270.

The operation of the horizontal slats 240, that is, the up/down movement of the multi-step horizontal slat type blinds or angular positions of the slats can be adjusted by means of a motor installed in the upper support section 210.

In detail, the motor transfers driving force to a pulley 130 connected to a blind rotating shaft 110 through a blind driving unit 100, and a length adjustment wire 250 and an angle adjustment wire 260 connected to rotating members 130 a and 130 b of the pulley 130 are wound around the rotating members 130 a and 130 b, which have diameters different from each other, according to the rotation of the blind rotating shaft 110 and the pulley 130, so that the horizontal slats can be moved up and down or angular positions of the horizontal slats can be changed.

Structures of the pulley and adjustment wires connected to the pulley can be modified in various shapes. That is, the pair glass window and door system of the present invention does not limit the structure of the pulley and adjustment wires, if the operation of the pulley and the adjustment wires can be adjusted by means of the motor.

Similarly, in a case of the corrugated fabric sheet blind as shown in FIG. 3, a corrugated fabric sheet 240 a is moved up and down by means of a length adjustment wire 260 a according to driving force of the motor applied to the length adjustment wire 260 a.

In addition, the pair glass window and door system 200 according to the present invention can remote-control the blind installed in the pair glass structure. To this end, a power supply unit having a special structure is provided.

FIGS. 4 a to 4 c are perspective views showing power supply terminals used for the pair glass window and door system equipped with a remote controllable auto blind according to one embodiment of the present invention, and FIG. 5 shows partially sectional perspective views illustrating structures of power supply units installed in a widow frame corresponding to power supply terminals shown in FIGS. 4 a to 4 c, in which FIGS. 5 a and 5 b show power supply units corresponding to power supply terminals shown in FIGS. 4 a and 4 b, and FIG. 5 c shows a power supply unit corresponding to a power supply terminal shown in FIG. 4 c. The power supply units and power supply terminals shown in FIGS. 4 a, 4 b, 5 a and 5 b are used for a sliding type window, and the power supply unit and the power supply terminal shown in FIG. 4 c and 5 c are used for various windows including the sliding type window.

Referring to FIGS. 4 a to 4 c and 5 a to 5 c, thin film tape type conductors 295 b and 295 b′ are attached to the slide protrusion 325 b and the slot 325 a of the slide rails, respectively, as a power supply wiring. In addition, power supply terminals 295 a and 295 a′ are installed at the door frame of the pair glass window and door system such that they can elastically make contact with the slide protrusion 325 b and the slot 325 a of the slide rails.

In the similar manner, when the thin film tape type conductor is attached to the slot 325 a, for example, when three pair glass structures are installed in one window frame as shown in FIG. 5 b, thin film tape type conductors having mutually different poles are attached to both slots 325 a so as to easily supply power to each pair glass structure.

The power supply terminals 295 a and 295 a′ include plane type first sections, and second sections having stopper protrusions 296 c and 296 c′ positioned at plane portions and longitudinal guide slots 296 d and 296 d′ positioned at lateral portions, respectively. In addition, the power supply terminals 295 a and 295 a′ also include planar bases 296 and 296′ having first fixing ends 296 a, 296 a′, second fixing ends 296 b and 296 b′, and elastic strip contacts 297 and 297′ fixed to the planar bases 296 and 296′, respectively.

The elastic strip contacts 297 and 297′ include bending type thin film contact strips having first ends 297 a and 297 a′ fixed to the first fixing ends 296 a and 296 a′ of the planar bases 296 and 296′ and guide strips formed with elongated holes 297 e and 297 e′ and inserted into the longitudinal guide slots 296 d and 296 d′ of the second sections in such a manner that stopper protrusions 296 c and 296 c′ of the second sections may protrude through the elongated holes 297 e and 297 e′. Ends 297 d and 297 d′ of the guide strips are formed as free ends. The elastic strip contacts 297 and 297′ can be prevented from being separated from the planar bases 296 and 296′ by means of the stopper protrusions 296 c and 296 c′.

The first fixing ends 296 a and 296 a′ and second fixing ends 296 b and 296 b′ of the power supply terminals 295 a and 295 a′ are formed with screw holes so as to fixedly secure the power supply terminals 295 a and 295 a′ to upper and lower portions or edge portions of the door frame of the pair glass window and door system.

According to one embodiment of the present invention, the first fixing ends 296 a and 296 a′ of the power supply terminals 295 a and 295 a′ are fabricated in the form of insert slots such that the power supply terminals 295 a and 295 a′ are easily assembled into or disassembled from the door frame of the pair glass window and door system.

In the meantime, the elastic power supply terminal 295 a′ shown in FIG. 4B includes the first and second sections which are bent at a right angle. The elastic power supply terminal 295 a′ is assembled to the door frame such that the first section of the elastic power supply terminal 295 a′ is rested at an upper end of the edge of the door frame. Thus, the elastic power supply terminal 295 a′ can be easily assembled into or disassembled from the edge of the door frame in a state that the door frame is coupled with the window frame without separating the door frame from the window frame.

Power can be supplied between the window frame and the door frame coupled with the window frame when the thin film tape type conductors make contact with the elastic strip contacts of the power supply terminals. Such a structure for the thin film tape type conductors and the power supply terminals may lead an effective power supply while preventing the power supply wiring from being exposed to the exterior.

As shown in FIGS. 4 c and 5 c, according to another embodiment of the present invention, a female type power supply terminal 290 b having a base formed with a fixing hole 293 b and positive and negative electrode terminals 291 b is installed at one of a lateral portion 320 b of the window frame 300 b and a lateral portion of the door frame 220. In addition, a male type power supply terminal 290 a having a base formed with a fixing hole 293 a and elastic positive and negative electrode terminals 291 a is installed at the other of the lateral portion 320 b of the window frame 300 b and the lateral portion of the door frame 220. Electric power is supplied when the male type power supply terminal 290 a makes contact with the female type power supply terminal 290 b.

Rear portions of the male type power supply terminal 290 a and female type power supply terminal 290 b are buried in the door frame or the window frame and are provided with electric terminals 292 a and 292 b connected to the elastic positive and negative electrode terminals 291 a or positive and negative electrode terminals 291 b so as to feed electricity.

The pair glass window and door system according to the present invention may supply power through the power supply terminals or control the operation of the blind driving unit by using a control unit, thereby remote-controlling the blind installed in the pair glass window and door system.

FIGS. 6 a to 6 c are perspective, front, side, and plan views of the blind driving unit used for the pair glass window and door system equipped with remote controllable auto blinds according to one embodiment of the present invention, and FIG. 7 is a block view showing an electric structure for automatically controlling the auto blinds accommodated in the pair glass window and door system according to one embodiment of the present invention.

Referring to FIGS. 6 a to 6 c and 7, the blind driving unit 100 includes a motor 40, a reduction gear box 20 for adjusting driving force and an R.P.M of the motor 40, a coupler 50 connecting a rotating shaft of the reduction gear box 2 with the blind rotating shaft 110 (see, FIG. 2) so as to transfer rotational force of the rotating shaft of the reduction gear box 2 to the blind rotating shaft 110, adjustment wires 250, 260 and 260 a (see, FIGS. 2 and 3) connected to the blind rotating shaft 110 and the blinds in order to adjust the up/down movement and angular positions of the blinds according to the rotation of the blind rotating shaft 110, a counter gear 60 formed with gear teeth and fixedly coupled to one of the rotating shaft of the reduction gear box, the blind rotating shaft and the coupler (for example, the counter gear 60 is fixedly aligned around the coupler in FIG. 6 b), a photo sensor 70 aligned adjacent to the counter gear 60 so as to detect the operation of the blinds caused by the adjustment wires through counting an R.P.M of the blind shaft by detecting the rotational movement of the counter gear 60, and a controller 30 for controlling the operation of the blinds by adjusting the driving direction (forward or reverse) of the motor and power supplied to the motor based on signals from a remote controller and the photo sensor 70.

The coupler 60 fixedly aligned around the coupler 50 may directly transfer rotational force of the motor 40, which has been reduced through the reduction gear box, to the blind rotating shaft, so the R.P.M of the coupler is equal to the R.P.M of the blind rotating shaft.

The R.P.M of the counter gear is counted by means of the photo sensor positioned adjacent to the counter gear. A beam radiated from the photo sensor may intermittently pass through the counter gear due to teeth of the counter gear, so that the photo sensor can recognize the R.P.M of the blind rotating shaft by counting the number of beams passing through the counter gear.

Such a measurement for the R.P.M of the blind rotating shaft by using the photo sensor 70 and the counter gear 60 makes it possible to measure the length of the blind adjustment wires wound around the blind rotating shaft. As a result, the development length of the blind can be recognized, so that it is possible to stop the operation of the blind when the blind is completely developed or shrunken.

The R.P.M of the blind rotating shaft counted by the photo sensor 70 is sent to the controller 30 and the controller 30 calculates the development length of the blind based on the R.P.M of the blind rotating shaft. Thus, if it is necessary to stop the operation of the blind, the controller 30 shuts off power being supplied to the motor, thereby stopping the operation of the blind.

The controller 30 includes a PCB panel, a signal receiving section 80 for receiving a remote-control signal from the remote controller so as to remote-control the blind, and a first CPU for controlling the operation of the blind by adjusting the driving direction (forward or reverse) of the motor and power supplied to the motor based on the remote-control signal received in the signal receiving section 80 and a signal transmitted thereto from the photo sensor in order to notify the development state of the blind.

The controller 30 controls the driving direction of the motor and the power supplied to the motor based on the remote-control signal generated from the remote controller. In addition, the controller 30 shuts off the power being supplied to the motor if the signal from the photo sensor indicates that the blind is completely developed or shrunken.

The controller 30 can be operated with DC, which has been converted from AC by means of a DC supply unit. The signal receiving section has a second CPU for discriminating receiving signals and the remote controller has a third CPU for recognizing a command of the remote controller. The remote-control signal from the remote controller and the optical signal from the photo sensor are processed in the first CPU so as to control the operation of the motor and the power supplied to the motor.

Preferably, the remote control operation is carried out using an RF signal or a voice signal so as to reliably transfer the signals regardless of obstacles.

The signal receiving section 80 of the controller has been set with a predetermined frequency band so as to receive the RF signal or the voice signal having a predetermined frequency band.

If the RF signal is used as the remote-control signal, buttons of the remote controller have been set such that signals having mutually different frequency bands can be generated when operating the buttons. Thus, various RF signals for moving the blind up and down and for adjusting the angular position of the blind can be created. In addition, if the voice signal is used as the remote-control signal, various voice tones are preset such that the blind can be operated corresponding to the voice tones.

Upon receiving the remote-control signal, the controller 30 adjust power applied to the motor in order to control the operation of the blind.

Meanwhile, according to the present invention, plural pair glass window and door systems can be installed in the door frame or the window frame (see, FIG. 1). In this case, the blinds accommodated in the pair glass window and door systems can be individually or integrally controlled by means of the controller.

Each signal receiving section of each controller provided in the blind driving unit of the plural pair glass window and door systems can be preset such that the signal receiving section only receives remote-control signals having a predetermined frequency band. In this case, if the remote-control signal having the predetermined frequency band has been received in the signal receiving section, the CPU controls the driving direction of the motor or power supplied to the motor so as to control the operation of the blinds.

As mentioned above, the remote-control signal may include a plurality of RF signals having mutually different frequency bands or a plurality of voice signals having mutually different voice tones.

Therefore, RF signals or voice signal, which can be received in each signal receiving section 80 of each controller, are predetermined. Thus, if the RF signal or the voice signal has been transmitted to the signal receiving section 80 of the controller from the remote controller or a user, only the controller, which has been preset with the predetermined RF signal or voice signal corresponding to the received RF signal or voice signal, may operate the blind. Thus, it is possible to individually control the blinds.

In addition, according to another embodiment of the present invention, all signal receiving sections 80 of the controllers can be set such that all signal receiving sections 80 receives a predetermined RF signal or voice signal. Accordingly, if the predetermined RF signal or voice signal is generated from the controller or the user, the controllers receiving predetermined RF signal or voice signal may operate the blinds. Thus, it is possible to simultaneously operate the plural blinds.

According to one embodiment of the present invention, predetermined remote control signals in the form of RF signals or the voice signals can be stored in a memory of the controller in order to allow the controller to memorize the operation of the blind corresponding to the remote control signals. In this case, if the remote control signal (for example, a remote control signal generated when the blind is in a stop position) is again generated, the controller operates the blind corresponding to the remote control signal.

Preferably, the controller includes an overload protector capable of shutting off power being supplied to the motor when over-current is applied to the motor.

The forgoing embodiments are merely exemplary and are not to be construed as limiting the present invention. The present teachings can be readily applied to other types of apparatuses. The description of the present invention is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art.

For instance, according to the present invention, the controller and the signal receiving section can be separated from the blind driving unit of the pair glass window and door system in such a manner that they are installed in the door frame adjacent to the pair glass structure or at an inner portion of the window frame.

As described above, the pair glass window and door system equipped with auto blinds accommodated in pair glass structures according to the present invention can individually or integrally remote-control the blinds regardless of obstacles by using the RF signals or voice signals while protecting the motor from over-current. In addition, the pair glass window and door system equipped with auto blinds has an improved power supply wiring capable of operating the blinds even if the window is opened or being opened. The pair glass window and door system equipped with auto blinds of the present invention can represent superior awning effect, lighting effect and thermal insulation and noise shielding effect, while protecting a private life and reducing energy consumption. In addition, a cost for laundering the blind and a cost for exchanging the blind can be reduced while preventing disease-causing bacteria, such as mites or viruses, from parasitically existing in a residential area by accommodating the remote controllable auto blinds in closed-type pair glass structures.
